Benefiting from the low cost of iron electrolytes, the overall cost of the all-iron flow battery system can be reached as low as $76.11 per kWh based on a 10 h system with a power of 9.9 kW. This work provides a new option for next-generation cost-effective flow batteries for long duration large scale energy storage.
This unique feature allows for cost-effective scaling, essential for large-scale applications. Developed using an advanced metal complex and membrane, Iron-Flow Batteries is based at the Paris Flow Tech platform – a premier hub for innovation in continuous flow chemistry.
Our iron flow batteries work by circulating liquid electrolytes — made of iron, salt, and water — to charge and discharge electrons, providing up to 12 hours of storage capacity. ESS Tech, Inc. (ESS) has developed, tested, validated, and commercialized iron flow technology since 2011.
Flow batteries are particularly well-suited for long duration energy storage because of their features of the independent design of power and energy, high safety and long cycle life , . The vanadium flow battery is the ripest technology and is currently at the commercialization and industrialization stage.
